The hairs lie flat when we are warm, and rise when we are cold. If we are too cold nerve impulses are sent to the hair erector muscles which contract. This raises the skin hairs and traps a layer...

Extreme weather can significantly affect the body’s ability to regulate temperature. Hypothermia occurs when a person has exposure to extremely cold temperatures for an extended period. In these instances, the body loses heat quickly, and heat production cannot keep up, causing a dip in body temperature. In addition to freezing temperatures, hypoth...
When a person has an infection, harmful microorganisms invade the body and multiply. These pathogens can thrive at typical body temperatures, but an increased temperature makes it more difficult for some of them to survive. For this reason, part of the immune response to infections is often a fever. This occurs when the body raises its own temperat...
Infants and older adults have a higher riskTrusted Sourceof thermoregulation disorders. The reason for this is that these individuals have a lower muscle mass, a decreased shiver reflex, and lower immunity. Older adults tend to have a lower body temperature and may not develop fevers when they contract a viral or bacterial illness. Sometimes, they ...
Certain medications can disrupt thermoregulation as a side effect, causing a temporary rise in body temperature. Some people refer to this as “drug fever.” Examples of medications that can have this effect include: 1. antimicrobials, such as antibiotics 2. nonsteroidal anti-inflammatory drugs (NSAIDs) 3. first generation anticonvulsants 4. antidepr...
Jul 30, 2023 · Thermoregulation is the maintenance of physiologic core body temperature by balancing heat generation with heat loss. A healthy individual will have a core body temperature of 37 +/- 0.5°C (98.6 +/- 0.9°F), the temperature range needed for the body's metabolic processes to function correctly.

- Skeletal system. The skeletal system is composed of bones and cartilages. There are two parts of the skeleton; axial and appendicular. The axial skeleton consists of the bones of the head and trunk.
- Muscular system. The muscular system consists of all the body muscles. There are three muscle types; smooth, cardiac and skeletal muscles. Smooth muscle is found within walls of blood vessels and hollow organs such as the stomach or intestines.
- Cardiovascular system. The cardiovascular system is comprised of the heart and the circulatory system of blood vessels. The heart is composed of four chambers; two atria and two ventricles.
- Respiratory system. The respiratory system consists of a series of organs; the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles and lungs (alveoli).
